How to SIM Unlock?

[smokarz]

Hey guys,

I have an AT&T M7 that is off contract and obtained an unlock code directly from AT&T.

Now, how do I go and SIM unlock my device?

Any help/suggestion is much appreciated.

Thanks

If you already have your unlock code thats a good thing. Now to use it, you must shut your phone down, insert a foreign sim card (from a different carrier than AT&T, borrow a friend's sim card if necessary), boot it up and you should get prompted to enter the sim unlock code. Once done your phone is sim-unlocked and will accept any carrier sim card. Your phone must be running the stock rom btw (or a stock-ish rom, will not work on Cyanogenmod for example but should work on ARHD).
